INK PRODUCT AND rnoonss or MAKING THE SAME" No Drawing.

The present invention relates to an. ink product and process of makingthe same, the invention being more particularly related to an improvedprinting ink product and. its process of manufacture.

Hitherto, in the art of lithographing, label printing and in similarlines of work, it has been the practice to print gold size on thesheets, allow the printing to dry to a certain extent and become tackey,and then to print thereon gold or other colored bronzes. Under thispractice it has been customary to carry out two distinct printingoperations;

first, the printing of the gold size, and then the printing of the goldbronze. In addition to these two distinct operations, there, is anotherattendant disadvantage in that the gold bronze which is printed in drypoW- dered form escapes into the surrounding atmosphere and thencesettles upon the print-- ing machines, paper stock and persons. withinthe printing room, the powdered gold bronze frequently having aninjurious efiect upon the persons inhaling the same.

The object and purpose of my invention are to provide a ready mixed goldor other colored bronze, having the character of an ink, either inliquid, semi-liquid or paste form, capable of being applied in oneprinting operation.

Another object is-to provide an improved product, as stated, wherebylithographers, label printers and others engaged in printing sheets ingold bronzes may perform their work quickly, economically, and withoutthe use of the powdered product.

Other objects will appear hereinafter.

My improved product consists of a mixture of cresylic acid, sulphuricacid, borax, flour, chrome yellow and gold bronze, together with avehicle which holds the other elements in a suitable ready mixed stateuntil they have been printed upon the sheet.

The best formula embodying my invention at present known to me, and thepreferred process of making, compounding and using the same, accordingto my present information, is as follows:

I make a product aggregate consisting, by weight, of about thirtypercentum of the Application filed Augustfi, 1929. Serial No. 384,487.

base ingredients, commercially referred to as pigments, and seventypercentum of :VGlllClB materials, although these proportions may bevaried greatly in accordance with the general character of the productto. be obtained,

whether in theform of athin liquid paste 2 ink, a semi-paste ink or afull paste ink. For the base or plgment aggregate, entering intotheproduct, I prefer to use ingredients in about the following proportions,byv weight, cresylic acid eight percentum,1s'ulphuric acid fourpercentum, borax fifteen-z it percentum, ,fiour sixty percentum, chromeyellow three percentum and gold bronzeten.

percentum. For the vehicle aggregate, en-

tering into the product, I prefer to take about ninety percentum ofwater and ten per-.

centum of varnish. Good results may be ob-- tained, however, when thematerials, both of the pigments and vehicles, are varied within thelimits of. twenty percentum of the proportions given.

All of the .materials fmay be introduced and mixed at the same time, andthey are cooked at about boiling temperature until thoroughlyfanduniformly mixed as a ready I 'mixed product in the state desired, thatis to say, a thin. liquid paste ink, a semi-paste ink or a full pasteink.

The improved ink. product produced asabove described is very economicalin manufacture, and is highlyeflicient as a ready.

mixed gold ink or bronze ink.

- The method of application may vary in accordance with the character ofthe printing press, device or apparatus used in printing. It is, ofcourse, well known that lithographers use either an offset printingmachine or a flat-bed litho press. When employing the offset machine thelithographers print from an aluminum or zinc plate. Where a flat-bedpress is used the printing is done from a stone. Label printers printfrom an electroplate. M ready mixed ink product can be used to a vantagein all of these methods of printing. f In pressprinting the. especiallyprepared plate is very sensitiveto grease. When the press is set inmotion a set of flannet rollers (kept moist by contact with water)pass'over the surface of the plate, slight- 1y Wetting it. Immediatelyfollowing the damp rollers are, the ink rollers, which distribute theready mixed ink product smoothly and evenly over the designs on thesurface of the plate. In this process, the thin coating of Waterprevents the ink product from adhering to the plate and only the designsthereof receive an application of the ink product.

It may be remarked here that Whenever the ready mixed gold or bronze inkproduct is too heavy, the same may be reduced to a suitable consistencyby the addition of a suitable grease compound, for instance, petroleumjelly .or

consistency of the product may be varied according to the character ofthe Work and ac- Z cording to the judgment of the manin'charge of thepress. i p While I have given above the best formula embodying myinvention at present-known 'to' me; and the preferred compounding andusing the same, I-reahze that in practice other combinations of pigments might be used besides those before mentioned, and the process ofcompounding may bevaried as experiencedictates, to produce the precisech'aracter and colorof ready mixed be desired for printing purposes. Itis to be understood, therefore,

making the product may be made therein, to which changes andmodifications I am entitled, provided the same are effected within thescope of the annexed claims.
